Applications: ’71-’92 Mazda 12A and 13B engines
MSRP: $55.00
The Racing Beat Oil Baffle Plate slows the return of engine oil as it drains from the engine into the pan. In slowing the oil’s return, air that has been suspended in the oil (as foam) is allowed more time to separate from the oil. Removing this trapped air improves the ability of the oil to transfer heat and reduces pressure drops at high rpm operation.www.racingbeat.com
714.779.8678

Applications: Mitsubishi EVO VII/VIII/IX
MSRP: $4,999.95
The AMS Dry-Sump System is designed to prevent oil starvation, lower oil temperatures, and add oil capacity all while freeing up horsepower. The failing point of most traditional wet-sump oiling systems is the risk of oil starvation due to oil slosh during racing conditions. Under the sustained g-forces of racing oil can be pushed to one side of the pan, causing vital engine components to be starved of oil. The AMS Dry-Sump System helps prevent this by providing constant oil pressure throughout the engine non matter the driving conditions. This not only aids in motor longevity but also frees up horsepower by removing oil from the pan where it can create parasitic drag on the crankshaft.www.amsperformance.com
